(1)Contingent consideration liability represents arrangements to pay the former owners of certain companies we acquired based on the attainment of future product release milestones and is reported in current accrued liabilities. We use a probability-weighted discounted cash flow model to estimate the fair value of contingent consideration liabilities. These probability weightings are developed internally and assessed on a quarterly basis. The remaining undiscounted maximum payment under these arrangements was $1.2 million as of March 31, 2021.
